Which protocol?
Usual suspects TR-069 OMA-DM LwM2M Can we have a Device Management over the telemetry protocol?
Kura Case Study MQTT CoAP/LwM2M
+M2M Integration Technologies
Message Queue Telemetry Transport (MQTT)
M2M Messaging Protocol Low Bandwidth / Low Power 2-way Communication Publish and Subscribe Hierarchical Topic Namespaces Data Payload Agnostic Device Initiated Connection Firewall-friendly SSL and Authenticated Large ecosystem
+Kura MQTT Topic Namespace
Introduction
Data Topics
Used for push of sensor data, metrics, or other data Example: [account_id]/[client_id]/...
Control Topics
Used for dynamic request/response interactions between clients Example: CTL/[account_id]/[client_id]/[app_id]/…
Separate data from control topics
Provides increased granularity on ACLs Allows for segregation of persistent and transient data
+Kura MQTT Resource Management
REST like
Request
CTL/[account_id]/[client_id]/[app_id]/GET/[resource_id] CTL/[account_id]/[client_id]/[app_id]/POST/[resource_id] CTL/[account_id]/[client_id]/[app_id]/PUT/[resource_id] CTL/[account_id]/[client_id]/[app_id]/DEL
EL/[resource_id]
CTL/[account_id]/[client_id]/[app_id]/EXEC
EC/[resource_id]
Response
CTL/[account_id]/[requester_client_id]/[app_id]/REPL
EPLY/ Y/[req_id]
+MQTT Request/Response
Responder (device1) Requester (manager1) Responder Subscribes on request topic: CTL/kura/device1/CONF-V1/GET/configurations
+MQTT Request/Response
Responder (device1) Requester (manager1) Requester Generates request metadata (for request payload): request_id: 1363603920892 request_client_id: manager1 Subscribes on reply topic: CTL/kura/manager1/CONF-V1/REPLY/1363603920892
+MQTT Request/Response
Responder (device1) Requester (manager1) Requester Sends MQTT request CTL/kura/device1/CONF-V1/GET/configurations
+MQTT Request/Response
Responder (device1) Requester (manager1) Responder Handles request and generates response using request specific parameters in the payload of the request
request payload
+MQTT Request/Response
Responder (device1) Requester (manager1) Responder Sends response to requesting client CTL/kura/manager1/CONF-V1/REPLY/1363603920892
+MQTT Request / Response
Response Codes: HTTP Like
response_code
200 (RESPONSE_CODE_OK) 400 (RESPONSE_CODE_BAD_REQUEST) 404 (RESPONSE_CODE_NOTFOUND) 500 (RESPONSE_CODE_ERROR)
response_exception_message
Optional and contains error message if an error occurred
response_stacktrace_message
Optional and contains a stacktrace
+Kura OSGi Management via MQTT
Bundle management
Retrieve Bundle information for installed bundles Start/Stop currently installed bundles
Deployment packages
Install new deployment packages (collections of OSGi Bundles) Update/Uninstall existing deployment packages
Configuration Management
Retrieve, review, update Service Configuration Support OSGi MetaType service descriptors
Remote Access
+CoAP
RESTful protocol designed from scratch IETF Transparent mapping to HTTP:
GET, POST, PUT, DELETE and URLs
Features for M2M scenario (observe & sms) Based on UDP, draft for using TCP
+
Open Mobile Alliance standard Device management on top of CoAP Object model: for D.M. or Applications
(IPSO)
OMA Lightweight M2M
+
Security Device Location Firmware Connectivity monitoring & management Lock & wipe
You can provide your own object to OMA
Standard Objects
+
/{object}/{instance}/{resource} Example: “/6/0” : get the whole GPS position instance “/6/0/2” : get only the altitude resource
